Application February 13, 1943, Serial No. 475,829

6 Claims. 1(01. 129-4) This invention relates to improvements in devices for binding or intersecuring leaves, pages, sheets or the like .in assembled book, magazine,

pamphlet, etc. formation, whereby the samemay be freely turned-one with respect to the other,

and yet, retained in their original arrangement; the invention having for .an object to provide such a device which .may be quickly and conveniently engaged with the particular sheets'to be bound thereby and if and when desired, may be as quickly and conveniently disengaged therefrom, then re-engaged therewith.

It is also an object of the invention to provide adevice of the stated character which, when op-,

eratively engaged withassembled pages or sheets, will occupy but .a minimum of space and will, in no way, interfere with .the desired fiat disposition thereof; moreover, will permit of selective removal of any one or more of such pages or sheets Without disengaging or disarranging the others.

A further object of the invention resides; in the provision of a binding device of simple, durable and one-piece construction, capable of being :produced in large quantities with maximum econo-i m1es.

Other objects of the invention will .be in part obvious and in part pointed outhereinafter.

In order that the invention and its mode of operation may :be, readily understood by those skilled in the art to which it appertains, I have in the accompanying drawing and the detailed description based thereupon, set out several embodiments of my invention.

In this drawing:

Figure 1 is an elevation of a booklet bound by a slightly modified form of the binding device, portions of the leaves of the booklet being broken away and other portions being-shown in section.

Figure 2 is an enlarged fragmentary detail in transverse section taken on the line 2-2 of Figure 1, looking in the direction in which the arrows point.

Figure 3 is a fragmentary elevation of the form of double sheet or foldable page such as bound in the form of invention illustrated by Figure 1.

Figure 4 is an elevation of the form of binding device illustrated by Figure 1.

Figure 5 is a side elevation of a somewhat modified form of binding device showing the same attached to the fragmentally illustrated' transverse section taken on the line 7-7 of Figure 5.

Having more particular reference to the drawing, and especially, to Figures 1, 2, 3 and 4 thereof, the device preferably consists of a rectangular flat, strip-like body l preferably made of form sustaining material, .such for example, as cardboard, heavy paper, plastics, wood, etc. A slot or way I is formed in and disposed longitudinally of the body I, and, as will be noted upon reference to Figures 1 and 4, extends through said body for the greater portion of its length. The width of the slot I may be either increased or decreased, according to the number and thickness of double leaves or foldable sheets to be engaged and bound thereby and likewise, the length of the body I" may be either increased or decreased, according to the lengths of the sheets which are to be received through its longitudinal slot or way I; thelatter, obviously, being likewise varied.

The double sheets or pages, such as indicated by the numeral 8, are adapted to be interconnected or bound by the device. Each of such sheets are provided with intermediately arranged longitudinally disposed fold lines 9. The lengths of the sheet, as above inferred, preferablyapproximately correspond to the length of the slot or way I in the body i in relatively aligned relationship. They may be folded along their fold lines 9 either before or subsequently to assembling. The thus assembled sheets are now inserted and passed through the slot 1 of the body l until said body engages in the intermediate longitudinal folds thereof, as is well known in Figure 2 of the accompanying drawing. The combined thickness of the assembled sheets engaged through the slot 1 is such that the adjacent inner straight edges of the slot or way I will bindingly engage with the other sides of the outermost sheets. In consequence, undesired sliding or shifting movement of the binding device upon or with relation to the sheets will be avoided and so, such sheets will be firmly and satisfactorily secured in book, booklet, magazine, pamphlet or similar arrangement.

I have shown a modified form of binding device in Figures 5, 6 and '7 of the accompanying drawing. In this embodiment of the invention, the binding device is shown to consist of a fiat, strip-like rectangular body, preferably constructed of substantially form sustaining material, l having an intermediately arranged and longitudinally formed slot or way I0 extending substantially throughout its length, as well shown To engage the binding device with the sheets, the latter are assembled in Figure 6. Right angularly disposed ears H are cut, stamped or struck from portions of the body I, preferably, in proximity to the opposite ends thereof and of the longitudinally disposed slot or way Ill. The formation of these ears II is such that they transversely span the longitudinal slot or way l and, at times, may engage in the cut away portions of the body I on the opposite side of said slot HI. In normal usage, however, the transversely disposed and relatively spaced ears H are bent or flexed outwardly in relatively opposite directions with respect to the opposite sides I,

or faces of the body l 1. e., to positions as Well therein and extending throughout the same for a portion of its length receiving said sheets therethrough, and relatively spaced ears on portions of said body extending across and beyond adjacent portions of said slot and laterally disposed in opposite directions with respect to the opposite faces of the body engaging and bearing upon adjacent portions of the outermost of said sheets.

3. A binding device, comprising, in combination withdouble sheets to be bound thereby, a fiat strip-like body of substantially form sustaining material having a slot formed therein extending llongitudinally throughout the same for a portion shown in Figure 7 of the accompanying-drawing.

Intermediately and longitudinally folded and relatively assembled sheets, generally indicated 5 by the numeral 8, are engaged through the slot or way Ill of the body l and are moved therethrough until the binding device engages said sheets directly adjacent their respective folds, as shown in Figure I, whereupon the outwardly bent ears I I are engaged with or over the opposite sides of adjacent portions of the outermost sheet 8, hence, causing the binding device to have substantially saddle-like engagement or connection with of itslength receiving said sheets therethrough, relatively spaced transversely disposed ears in- "tegjral with a portion of the body extending transthe sheets over their respective folded portions.

This saddle-like engagement, as between the binding device and the sheets bound thereby, obviously will serve to prevent relative shifting movement between the device and the sheets and consequently, insurance of proper interconnection of the sheets is efiected with the resultant retention thereof in the desired assembled relationship.

I claim:

1. A binding device, comprising, in combination with double sheets adapted to, be bound thereby, a body of substantially form sustaining material having a longitudinally disposed slot formed therein and extending throughout the same for a portion of its length receiving said sheets therethrough, and relatively longitudinally spaced ears on a portion of said body and laterally disposed in opposite directions with respect to the opposite faces thereof engaging and bearingupon adjacent portions of the outermost of said sheets.

2. A binding device, comprising, in combination with double sheets adapted to be bound thereby, a body of substantially form sustaining material having a longitudinally disposed slot formed versely across portions of said slot and laterally outwardly disposed in relatively opposite directions with respect to the opposite faces of the body engaging and bearing upon adjacent portions of the outermost of said sheets.

4. A binding device, comprising, in combination with double sheets adapted to be bound thereby, a body having a slot formed therein receiving said sheets therethrough, and ears on a portion of said body disposed transversely of the slot and arranged outwardly of the same and the body in opposed relation, said ears engaging and bearing upon adjacent portions of the outermost of said sheets.

5. A binding device, comprising, in combination with double sheets adapted to be bound thereby, a body having a slot formed therein receiving said sheets therethrough, and transversely disposed r ears struck from said body spanning said slot and having their free portions laterally spaced from the opposite sides of the body, said ears engaging and bearing upon adjacent portions of the outermost of said sheets.

6. A binding device, comprising, in combination with double sheets adapted to be bound thereby, a body having a slot formed therein receiving said sheets therethrough, and transversely disposed ears struck outwardly from said body spanning .said slot and having their free portions laterally spaced from the opposite sides of the body, said ears engaging and bearing upon adjacent portions of the outermost of said sheets.
